Chris Chambliss delivered a two-run double in the ninth inning last night to give the Atlanta Braves a 3-2 triumph over Houston in Atlanta in a game marred by a fight in the stands between Astro first baseman Cesar Cedeno and a fan.

Claudell Washington was hit by a pitch by reliever Joe Sambito to lead off the Braves' ninth and reliever Billy Smith (1-1) gave up a single to Bob Horner. Eddie Miller pinch-ran for Horner and Chambliss lined his double to left center to make a winner of Rick Camp (8-2).

Cedeno was ejected from the game after he engaged in a scuffle with a fan who Cedeno said called him "killer" after Cedeno struck out to end the first inning.

A Brave spokesman said that both Cedeno and the fan involved agreed not to file any charges in the incident.

Cedeno was convicted of involuntary manslaughter and fined $100 in January 1974 after a 19-year-old woman was shot to death in Santo Domingo, Dominican Republic.

"I have my family along on the trip," said Cedeno. "I do not enjoy anybody calling me anything that I'm not. Just for the fact that somebody paid $6, I don't have to be insulted . . . The only thing I regret is that I got thrown out of the game and we ended up losing the game. I'm sorry for that. I do prefer not to comment on exactly what he was calling me. That's why I took action. Because he was talking directly to me and he was doing it for two days."

"I'll have to find out a lot more about this," National League President Chub Feeney said in New York. "I'll have to get the umpires' report and possibly see films. Obviously, we don't condone that sort of thing."
